Computer Associates International, Inc (CA) recently announced that it won the best application/Management System Award at the Linux World China 2004 Conference. This shows that CA has once again affirmed its efforts to promote the development of Linux and open source communities. With the development and maturity of Linux, more and more enterprises begin to apply open-source software.

Building private CAs and SSH configuration servicesBefore you learn how to build a private CA, familiarize yourself with the basic concepts: CAS represents a certification authority, PKI represents a public key infrastructure, a registry of RA certificates, and a revocation list for CRL certificates. There are some encryption methods involved in architecting the CA, and here are some types of encryption to

Openssl is an open-source implementation of SSL (applications can be downloaded for free). It is a secure and confidential program that is mainly used to improve the security of remote login access. It is also one of the tools currently used in encryption algorithms and has powerful functions.Openssl provides a security protocol for network communication security and data integrity, including key algorithms, common key and certificate encapsulation management functions (
